Can children own money?
That is a complex question in many legislations. Children may be able to own money and other property, in their own right, yet be under the legal guardianship of their parents.
- Parents can generally control how minors spend their money.
(A child saying "Great-uncle left me a million bucks in his will? Great, let's buy a hundred tons of chocolate." would be blocked by the parents and that would be upheld by a court.)
- Parents may be required to take care to preserve the property of their children.
(A parent saying "Great-uncle left you a million bucks in his will? I'll invest it in lottery tickets, one of them is bound to be a winner." might be blocked by a court.)
- Children with their own income may be required to contribute to household expenses.
(A parent saying "So you got a summer job? Put your wages into the tin for the summer rent." may be upheld by a court.)
In your specific case, it would matter where you live, where the money comes from, and possibly how old you are.
